South Korean alloy producer Sphere will buy a 10pc ownership and offtake stake in the developing 72,000 t/yr Excelsior nickel cathode, sulphate and mixed hydroxide precipitate (MHP) project in Indonesia.

Nickel production at Excelsior is scheduled to start in April–June 2026, Australian producer Nickel Industries told Argus on 2 January.

Sphere will take 10pc of Excelsior's nickel production as nickel cathode when the project opens, Nickel Industries told investors. It has also signed an additional market-priced nickel offtake deal, Nickel Industries added, without disclosing the volumes involved.

Excelsior is currently a joint venture between Nickel Resources and Chinese producer Decent Resource. Sphere's ownership stake will come from Decent's holdings, Nickel Industries told investors.

Sphere supplies nickel metal and alloys to multiple global aerospace producers. It recently signed a 10-year metal supply agreement with US aerospace developer SpaceX.

Sphere's investment into the Excelsior project comes just weeks after Indonesia's trade ministry issued regulations around mineral export benchmark prices, sparking market discussions about a possible export tax on processed nickel products.

Indonesian processors produced 360,000t of nickel-equivalent MHP in January-September 2025, up by 64pc on the year. They plan to boost the country's nickel-equivalent MHP capacity by 658,000 t/yr in 2025-27.

Argus' MHP nickel payable 37pc min fob Indonesia price was last assessed at $132.50/metric tonne unit (mtu) on 26 December, up from $121.90/mtu on 27 December.
